Preparation method of stainless steel wire modified by Bi2WO6 glass ceramics for dynamic intercepting

Abstract

The invention discloses a preparation method of stainless steel wire modified by Bi2WO6 glass ceramics for dynamic intercepting, and belongs to the technical field of cooking fume purification treatment. The preparation method comprises the following steps: preparing Bi2WO6 glass ceramic micropowder; treating the surface of a stainless steel wire for the dynamic intercepting by adopting thermal spraying, and preparing the stainless steel wire for the dynamic intercepting with a Bi2WO6 glass ceramic glaze surface; putting the stainless steel wire for the dynamic intercepting with the Bi2WO6 glass ceramic glaze surface on a dynamic intercepting device, thus realizing self-cleaning and VOC (Volatile Organic Compound) degradation functions of the stainless steel wire for the dynamic intercepting with the Bi2WO6 glass ceramic glaze surface. According to the preparation method disclosed by the invention, heat energy and optical energy of a cooking fume purification hearth per se are fully utilized, energy saving and environment protection are realized, multiple functions are realized, and the technology is simple.

Description

technical field [0001] The present invention relates to a Bi 2 WO 6 A method for preparing glass-ceramic modification, in particular to a stainless steel wire Bi for dynamic interception 2 WO 6 The invention discloses a method for preparing glass-ceramic modification, which belongs to the technical field of oil fume purification treatment. Background technique [0002] The fume exhaust gas produced in catering cooking, industrial processing and other occasions contains a large amount of pollutants. In order to protect environmental resources, these fume exhaust gases must be purified before being discharged into the air. The purification rate of traditional fume air purification equipment is often low. , the exhausted air after purification treatment still contains a lot of oil fumes and other pollutants, which leads to an increase in the PM2.5 index in the air.

[0002] The fume exhaust gas produced in catering cooking, industrial processing and other occasions contains a large amount of pollutants. In order to protect environmental resources, these fume exhaust gases must be purified before being discharged into the air. The purification rate of traditional fume air purification equipment is often low. , the exhausted air after purification treatment still contains a lot of soot and other pollutants, resulting in an increase in the PM2.5 index in the air

[0003] Practice has proved that it is an effective means to improve the interception rate to install a dynamic interception oil fume purification device at the air inlet at the front end of the oil fume air purification equipment. The oil fume air purification device in the prior art is mainly composed of a central plate and radial It consists of a number of spokes radiating outward. When working, the power drive device of the oil fume air purification equipment drives the spokes to rotate through the central disk, so that solid particles such as oil fume entering the oil fume air purification equipment hit the spokes and move outward due to centrifugal force. Throwing out can intercept a large amount of oil fume and pollutants, and effectively improve the oil fume purification rate. However, the inventor found in the process of implementing the application that the oil fume interception rate of the prior art dynamic interception oil fume purification device has not yet reached the desired effect.
